In this explosive episode of Pod of Inquiry, retired cardiologist and vitamin C expert Dr. Thomas Levy reveals groundbreaking research showing that over 95% of heart attacks may be directly caused by hidden oral infections — often from root canals and untreated dental decay & how root canals trigger heart disease .
No pain. No symptoms. Just silent infections pumping deadly toxins into your bloodstream every time you chew.
What You’ll Learn in This Episode:
- Why 100% of over 5,000 tested root canals were found toxic — more than botulism
- How these oral pathogens directly cause heart attacks, strokes, and chronic disease
- Why standard dental X-rays miss 75% of infections
- The one scan (3D Cone Beam CT) that could save your life
- Dr. Levy’s personal story of reversing chronic inflammation after decades of illness
- How oxidative stress links dental infections to nearly every modern disease
- The truth about iron, iodine, and the ADA’s biggest blind spot
You can’t fix your health if your mouth is making you sick.
If you have heart disease, autoimmune issues, or unexplained fatigue — your root canals might be the missing link.
📘 Based on Dr. Levy’s book “Hidden Epidemic”, this conversation could save your life — or someone you love.

Guest Biography
Thomas E. Levy, MD, JD
Dr. Levy is a board-certified cardiologist and a bar-certified attorney. After practicing adult cardiology for 15 years, he began to research the enormous toxicity associated with much dental work, as well as the pronounced ability of properly administered vitamin C to neutralize this toxicity. He has now written eleven books, with several addressing the wide-ranging properties of vitamin C in neutralizing all toxins and resolving most infections, as well as its vital role in the effective treatment of heart disease and cancer. Others address the important roles of dental toxicity and nutrition in disease and health.
Recently inducted into the Orthomolecular Medicine Hall of Fame, Dr. Levy continues to research the impact of the orthomolecular application of vitamin C and antioxidants in general on chronic degenerative diseases. His ongoing research involves documenting that all diseases are different forms and degrees of focal scurvy, arising from increased oxidative stress, especially intracellularly and that they all benefit from protocols that optimize the antioxidant levels in the body. He regularly gives lectures on this information at medical conferences around the world.

- Featured book: “Hidden Epidemic”
02:59 – How Dr. Levy Got Started
- Traditional cardiologist in Colorado Springs (1993-94)
- Met Dr. Hal Huggins, a biological dentist
- Dr. Huggins treated patients with advanced chronic diseases (ALS, Alzheimer’s, Parkinson’s)
04:31 – The Pivotal Moment
- Witnessed elderly patient with advanced neurologic disease become more animated during extensive dental work
- Patient received 50 grams of IV vitamin C
- This observation sparked 30-year quest to understand vitamin C and dental health
05:51 – Transition from Cardiology
- Dr. Levy had already tapered down his cardiology practice
- Dr. Huggins made generous consultative offer
- Eventually attended law school during this transition
08:05 – Oxidative Stress Explained
- Definition: excess electron-depleted biomolecules in cytoplasm
- Key insight: disease IS the oxidation, not something separate caused by oxidation
- All effective treatment requires two components:
- Repair old oxidation
- Stop new oxidation
- Toxins = pro-oxidants (synonyms)
12:01 – What is CAP (Chronic Apical Periodontitis)?
- Abscess at the root tip of a tooth
- Indicates a dead tooth with necrotic pulp
- Similar pathological impact as root canals
- Dr. Weston Price and Dr. Boyd Haley research mentioned
13:49 – The 5,000 Root Canal Study
- Dr. Boyd Haley (University of Kentucky) tested over 5,000 consecutively extracted root canals
- 100% were highly toxic
- More toxic than botulism
- Orthodontically extracted normal teeth tested completely negative
15:43 – The Shocking Discovery
- Friend’s case: painless abscessed tooth revealed on cone beam scan
- Key finding: Most infected teeth are pain-free
- 7-10% of all adults have at least one abscessed tooth
17:58 – Impact on Children
- Children with leukemia and brain cancer often have infected teeth
- Need same dental attention as adults
- Case examples of children with brain tumors having mouths full of infected teeth
19:21 – Importance of Testing
- 3D Cone Beam CT (CBCT) examination is essential
- Regular dental x-rays only catch 20-25% of problems
- Must be part of basic workup like blood panels
22:25 – Follow-up Testing Example
- Friend had teeth removed, did well for 6-7 years
- Developed breast lumps
- Repeat cone beam showed two more abscessed teeth
- Lumps resolved after extraction
23:28 – Mechanism of Toxin Spread
- Chewing forces express pathogens into bloodstream, lymphatics
- More effective than injection
- Infected teeth continuously seed infection throughout body
26:03 – Why Dentists Don’t Use Cone Beam
- More cone beams available now than 10 years ago
- Creates more business for dentists
- Resistance to change from established routines
- Traditional dentistry does more damage than any other profession
- Biological dentistry does more good than any other profession
28:43 – How Infections Affect the Heart
- Pathogens from chewing enter venous blood
- Travel through low-pressure system to left ventricle
- 25% of blood goes to coronary arteries with high pressure
- Pathogens impacted against vessel walls with systolic force
29:52 – The Landmark Study (2006)
- Dr. Ott examined 36 patients with coronary artery disease
- Performed angiogram with atherectomy (arterial “roto-rooter”)
- Found over 50 species of bacteria, viruses, fungi in plaques
- Present in 38 out of 38 patients (100%)
31:25 – Inflammation and Vitamin C
- Acute inflammation = acute deficiency of vitamin C
- Monocytes contain 80-fold (8,000%) more vitamin C than surrounding blood
- Monocytes act as vitamin C delivery system
- Chronic infection leads to chronic immune response and atherosclerosis
33:50 – Bold Claim
- Over 95% of all heart attacks are directly caused by oral pathogens
35:56 – Dr. Levy’s Personal Experience
- Struggled with high CRP (C-reactive protein)
- Had root canal removed 10 years prior
- Experienced angina while running
- Decided to have tonsils removed
37:41 – Dr. Joseph Issels’ Work (1950s)
- Treated metastatic cancer patients
- 98% had 2-10 infected teeth
- 15-20% had heart attacks during treatment
- Found 100% of tonsils grossly infected despite normal appearance
- After tonsillectomies: no more heart attacks
40:00 – Dr. Levy’s Tonsillectomy
- Right tonsil appeared normal
- Left tonsil (same side as previous root canal) was full of pus
- CRP normalized for first time in 15 years after surgery
41:11 – Alternative Tonsil Treatments
- Ozone gas injections directly to tonsils
- Methylene blue drops on tonsils
- Both are powerful anti-pathogen agents
- Can avoid tonsillectomy in many cases
- Monitor with CRP levels
42:28 – Sinusitis Connection
- 70% of chronic sinusitis patients have infected teeth in upper jaw
- Must address dental infections for sinus treatment to work
- Cone beam reveals infections in both jaws
44:00 – Dr. Weston Price’s Research (1930s-40s)
- “Rock hard science”
- Took root canal from patient with heart disease
- Implanted under rabbit skin
- Rabbit died in one week from heart attack
- Same tooth killed 30-40 consecutive rabbits with coronary disease
- Similar results with arthritis
46:08 – Gut Microbiome Connection
- Oral and gut microbiomes closely related
- Pathogens swallowed from mouth affect gut
- “All things begin at the gut” may actually start in the mouth
47:38 – Rapid Virus Recovery Book
- Almost called it “Rapid Gut Recovery”
- Chronic pathogen colonization present in nose/throat
- Hydrogen peroxide nebulization strips biofilm, kills pathogens
- Many people have normal bowel movements within 24-48 hours
48:26 – Gut Healing Timeline
- Gut epithelial barrier cells have 3-5 day half-life
- Gut turns over completely every week
- Chronic gut conditions are actually “chronically induced acute insults”
49:46 – Case Examples
- Young man cured of Crohn’s disease with peroxide nebulization
- Family cured of black mold illness
- Stopped hospitalizations, ICU visits
51:56 – Dr. Huggins’ Wisdom
- “You can’t dry off while you’re still in the shower”
- Must stop source of oxidative stress, not just treat symptoms
53:06 – The Iron Problem
- Enriched foods contain metallic iron filings since 1940s
- Worst possible thing for gut health
- Chronic gut irritation from iron ingestion
54:49 – Iodine and Hashimoto’s
- Denmark studies showed Hashimoto’s increased after iodine supplementation
- Similar pattern to iron issue
56:06 – Ferritin Levels
- Laboratory reference range up to 400
- Ideal level around 30
- High ferritin = major cardiovascular risk
57:12 – Hydrogen Peroxide Explained
- H2O2 naturally abundant in body
- Respiratory cells secrete peroxide to kill inhaled pathogens
- Leaves only water and oxygen after killing pathogens
- Hydrates and oxygenates tissue
- “Perfect remedy” – cheap and available
